SPECIFICATION forming part of Letters Patent N0. 508,668, dated November14, 1893.

To aZZ whom it may concern:

Be it knownv that I, NORMAN O. BAssETT, a citizen of the United States,residing at Lynn, in the county of Essex and State of Massachusetts,haveinvented certain new and useful Improvements in Snow-Sweepers, of whichthe following is a specification.

This invention relates to improvements in snow sweepers for railways andcomprises improvements in the arrangements of the motors and sweepers,and the construction of the sweepers themselves.

In the accompanying drawings, Figures 1 and 2 are elevations, fromopposite sides, of the end of a car provided with myimproved sweepingdevices. Fig; 3 is a plan view of the same. Fig. 4 is a detail. a

The car or carrier, A, for the sweeper has usual or suitable runninggear andmotive devices, such as truck a and electric motor a. Projectingforward from the carrier is a frame I) which together with the caritself supports the sweeper. This frame is preferably rigid with the cartimbers, but it is preferred to give it additional support in the shapeof one.

or more truss rods 1), running from the outer end of the frame to theupper part of the car. The one shown in the drawings is attached to theframe at or near the outer end of the diagonal axis on "which thebroomcarrying frame turns. This sweeper consists of a rotary broom or drum 0and a motor D mounted in a frame E hung on pivot or rock shaft F, themotor and drum being on opposite sides of the shaft so as tocounterbalance one another. The motorindicated is an electric motorregulated or controlled independently of the car motor, and connectedvto the circuit by flexible connections, necessitated by its movements.The motor is geared to the sweeping drum in any suitable manner, as bymeans of gear wheels indicated in dotted lines in Fig. 3, or by beltingor otherwise. In any case the gearing shouldbe adapted to vibrate withthe motor and drum around the pivot shaft F, so as to preserve theconnection in all positions of the drum. The gearing is incased in acasing or cover G, carried by frame E.

To lower and raise the drum or rotary broom 0, means are provided fortilting the frame E and holding it in any requiredposition. Such meansmay Consist of a screw S, provided with a'handle H and a nut n, which isheld from rotation by guide Land is therefore moved up and down inaccordance with the rotation of the.scre\v. The motion of this nut ispreferably transmitted to the frameE, through a buffer spring 0, whichtherefore serves as a yielding support for the frame, so as to take upjars or vibrations thereof, thus preventing 6c pounding. The nutn,serves as an adjustable support for the frame.

The rotary broom or sweeper C, is preferably divided into two parts,with the driving gear between them. Each part consists of 6 5 wheels orheads 0, 0' connected by framing pieces which carry the brushes orbrooms proper B. Each brush R consists of steel or other strips boundtogether and provided with a front plate or cutting or striking plate P,of steel, which acts as a cutter for ice and compacted snow, andprepares the way for the action of the brush R which, projectingslightly below the plate, effectually clears the track of loose snow,and is prevented from clogging by the plate. The drum, is as usualplaced at an angle across the track and the forward end of each part ofthe drum is utilized as an ice cutter, the.head or wheel 0 beingprovided with cutters or teeth T, which breakinto the mass of ice andsnow and preventthe jamming thereof against the heads. These teeth areformed both on the rims and the spokes of the wheels, as shown in Figs.2 and 4. OasingsV are provided for the drums. 8

What I claim as new, and desire to secure by Letters Patent, is

1. In a sweeper the combination of the car 'rier the frame pivotedthereon and the rotary broom and motor geared together, and supyo portedon said frame on opposite sides of the pivot.

2. In a sweeper, the combination of the carrier, the frame pivotedthereon, the motor and rotary drum su pportedon said frame on oppositesides of its pivot, and gearing connecting the motor and drum, and acasing for said gearing, all turning around the said pivot of the frame.

3. A sweeper having a carrier, a pivoted 10o and counterbalancedframethereon; a rotary broonr'carriedhysaid frame;-and anadj usting devicefor said frame, consisting of a screw and nut engaging with the frameand carrier. y

4. A- sweeper havingza carrierg-a pivoted and connterbalancedframethereon, airotary broom carried by said frame, asnp'p'o'rt onth'ecarrier, and a spring or cushion placed between said frame and support.

5. A sweeper comprising a carrier, a broom carrying frame pivotedthereon, on a horizontal axis 1a*snpporton-the carrierron theoppositeside of the axis from the broom and a spring interposed between" saidframe and support.
